[thorn bramble]

i forgot you HATE definining local variables

[surreal path]

@flat nymph u trying the iso now

[flat nymph]

Which

[surreal path]

^

[flat nymph]

I think this tripple faulted

I'mma try it again

[surreal path]

try

if it triple faulted too

ur machine just is racist towards nyaux

osism

[flat nymph]

2 machines

Or Nyaux has some skill issue with AMD

[kind root]

its because u flashed it

[surreal path]

💀

[flat nymph]

yeah

[surreal path]

nah i dont use any intel only instructions

[flat nymph]

fucked nuyaux

then flashed my pc

[surreal path]

💀

💀 💀

[flat nymph]

doesn't tripple fault

[surreal path]

okay

so @thorn bramble theory is probs right

[flat nymph]

I have serial port

So

remove flanterm

Write to that

[surreal path]

framebuffer is probs above 4GB

k

[thorn bramble]

pmos works tho

¯_(ツ)_/¯

[flat nymph]

pmos doesn't use hhdm

temps mappings for everything

and framebuffer in userspace

[thorn bramble]

ah i see

yeah it is probably that lol

i am a genius

[flat nymph]

although I've also had some skill issues with framebuffer on other PCs

[thorn bramble]

(hopefully)

[surreal path]

ok try and check serial port

[surreal path]

well im happy its not a problem with my code (it is in that i die if the framebuffer is outside 4gib but fuck u)

[flat nymph]

limine does work though

and it should be using hhdm (?)

[surreal path]

i dont know ask mint

[flat nymph]

as in limine gives picture

[surreal path]

i didnt make limine

[flat nymph]

the serial is quiet

but it's not tripple faulting

Can you set lower baud rate?

[surreal path]

it should not be

k hold on

[flat nymph]

one of the PCs seems to be having a serial port skill issue

[thorn bramble]

make sure you aren't using ft_ctx anywhere anymore

[flat nymph]

or both

I have a third PC

[surreal path]

im not

[flat nymph]

But I'm using it as a server...

[surreal path]

sprintf only prints to serial

[flat nymph]

To host home assistant among other things

So without it home dumb

[surreal path]

okay i set both dlab registers to 0x03

i dont know how much that is in baud rate

[flat nymph]

I don't see you waiting for buffer to be empty

[kind root]

just set a slower baud rate

to prevent cable skill issue

[surreal path]

sprintf

[flat nymph]

And that as well

[flat nymph]

But it's having skill issue on pmOS with 9600

[surreal path]

thats what imt rying to do

[flat nymph]

But that PC has a 12 years old Aerocool PSU

(fire hazard)

Idk how it survived that long

@kind root probably knows

What I'm talking about

[kind root]

lol

[surreal path]

okay

lets do the math

so 0x3 is 11

[flat nymph]

13

At least that's what I have set in pmos

Maybe that's why it's not working

[surreal path]

for both dlab registers?

significant and least signicant

?

or not

[flat nymph]

?

No

Idk

Ask chatgpt

It probably knows

[surreal path]

what

how does it know ur code

what

[surreal path]

13 what

[flat nymph]

lol my drawer has some interesting finds

[surreal path]

can isee ur serial init code

[kind root]

pmos for mips when

[surreal path]

nvm

[flat nymph]

it's the same as yours

but ask chatgpt

mine is also half broken

[surreal path]

its now 9600 baud

[flat nymph]

and I can't find the third serial lead

[surreal path]

try

9600 baud

[flat nymph]

chatgpt says it's 12 btw

ates thind!

[surreal path]

well it kinda worked

[flat nymph]

d its me

[surreal path]

anyways now its not a bug i can go back to WORKING ON ROUTE IRQ

IN PIECE

PEACE

@kind root most stable framebuffer

(its a bug not a feature nyaux does not support above 4gb framebuffers)

[flat nymph]

ask @wicked loom

[surreal path]

ask her what

lol

[kind root]

lfg

[flat nymph]

why flanterm no work on my pc

[surreal path]

looking for games?

play cs2

with @bleak cedar

[flat nymph]

Ok it was a PSU issue hi world its me nyaux hates this framebuffer land!

@surreal path can you install idt before flanterm, and try to initialize it?

[surreal path]

k

oh yeah

nyaux is way faster when not printing shit

like

WAY

faster

on tcg btw

anyways

@flat nymph

go and try ig

[kind root]

4745/s 💀

[surreal path]

(ON TCG)

😡

[kind root]

fair

[flat nymph]

I think I need a PXE server

And I could log to network in pmOS

This should probably be the easiest thing to implement

[surreal path]

wel

[kind root]

nyaux forgot \r\n

[surreal path]

i did not

😡

[kind root]

\r as well?

[surreal path]

i dont do /r lol

just /n

[flat nymph]

I think my PCs now hate me for booting Nyaux on them

[surreal path]

lol

[kind root]

serial wants both

[surreal path]

anyways cool nyaux runs

[surreal path]

k hold on

[flat nymph]

and tripple faults

[surreal path]

[tawdry mirage]

well you could configure the host to translate \n to \r\n via termios

[tawdry mirage]

not sure if you can tell screen to do that but ```
$ stty -F /dev/ttyS0 speed 115200 raw nl
$ cat /dev/ttyS0

[surreal path]

oh yeah thats normal

i dont support 32 bit hpets

[kind root]

its normal to triple fault?

[surreal path]

so nyaux didnt triple fault from the serial info it seems

no]

there is an idt installed so if we were abt to even fault

it would have been caught

idk why it didnt

but not my problem idc i dont support framebuffers over 4gib

:^)

i dont want to think about it i dont hear you lalalalala

[flat nymph]

It could still be a you problem

[surreal path]

prints all this then triple faults? not my problem

[surreal path]

nah not rlly

if it panicd

its fine

[kind root]

doubt

[surreal path]

doubt x2 ur statement

do not try to make me die from pain trying to debug something for hardware i dont support

i.e framebuffers over 4g

i do not care i do not want to deal with it and it runs on most hw fine anyway

[flat nymph]

This PC's memory map

Framebuffer is at 0x7C00000000

[surreal path]

also it is a waste of time for me to be debugging this, i need to be the fourth hobby os kernel with ec

[flat nymph]

At 534GB

Because why not

[surreal path]

yea thanks whoever made ur mobo

:)

amazing place to put a framebuffer btw

:)\

[edgy pilot]

I don't think that's the case with newer versions

just memmaps and kernel

[kind root]

the gpu probably has a large bar that cant fit under 4g

[surreal path]

probs

[kind root]

so the bios obviously allocated it higher

[surreal path]

btw what is a bar

like a chocolate bar?

like u eat it?

nom nom?

[surreal path]

whats the difference between edge leveled triggered interrupts

and level triggered interrupts

[molten grotto]

edge triggered gets triggered when the signal changes from low to high (or from high to low depending on the polarity), level triggered continuously triggers when the signal is high (or low based on the polarity)

[surreal path]

will i just default the flag to edge triggered

[kind root]

no

[surreal path]

oh

should i default it to level triggered?

[molten grotto]

for isa irqs the default is active high + edge iirc

then if there is an override you take whatever the override specifies

[surreal path]

okay

[molten grotto]

but it also depends on what exactly you are configuring, for eg. the acpi sci the default is active low + level

[surreal path]

acpi sci?

[molten grotto]

the interrupt that uacpi installs

[surreal path]

oh okay

whats intr init, extint etc etc

i know what smi is

but anything else of this

is there an sdm page/chapter that describes that these signels are?

[molten grotto]

probably but for the io-apic you don't really need any of the others than fixed (or maybe lowest priority if you want)

[surreal path]

okay

[molten grotto]

and maybe nmi if you want to create some sort of watchdog that interrupts the cpu regardless whether interrupts are enabled or not

[surreal path]

is it important to know what these signels are?

[surreal path]

?

[molten grotto]

likely no at least at this stage

[surreal path]

okay

did we just

...

fault

nvm

wait not nvm

why did he fault

this vm run?

weird

time to test the vm 15 times

tested it 15 times

no fault

weird

@molten grotto is extracting the flags like this correct?

from the isos

also they are all zero for some reason

ummm

i think thats correct?

[molten grotto]

polarity is low 2 bits, trigger is the next 2 bits after that

[surreal path]

101 is init

[molten grotto]

the override flags don't encode anything else than polarity and trigger

[surreal path]

oh okay

[surreal path]

why does polarity need 2 bits

same with trigger

cant they just be one bit each

umm

[molten grotto]

well there are also some special values

[surreal path]

OHHHH

that makes sense

[molten grotto]

https://uefi.org/htmlspecs/ACPI_Spec_6_4_html/05_ACPI_Software_Programming_Model/ACPI_Software_Programming_Model.html?highlight=madt#mps-inti-flags

[surreal path]

thanks

[surreal path]

first guy is active high and edge triggered

second is none

so no override map as ud like

[kind root]

ew acpi 6.4

[surreal path]

this is genuinely so cringe but idc

[surreal path]

acpi follows a pattern thats similar to the apic bits so im doing this

[molten grotto]

it just happened to be what I had visited

[surreal path]

oh yeah

im bitshifting the wrong way everywhere

its <<

not >>

nvm im not

cool

56 not 32 whoops

most normal nyaux code

lit repeated code

fuck why is polarity reversed

um

code

[silver yarrow]

brother

[surreal path]

how is thing 0b10

yes borther

brother

what is up brother

@silver yarrow ??

[silver yarrow]

nothing just that the code is uhhh

great

[surreal path]

i know its shit

im just trying to speedrun ioapic rn

[silver yarrow]

hey you said it

[surreal path]

it is true

[surreal path]

anyways

so if thing is 0

why is it 0b10

signed bit?

no?

[silver yarrow]

its.. not

if its 0 then its 0b00

[surreal path]

so why tf is it return -1

[silver yarrow]

wtf is %b

sec

[molten grotto]

binary print

[surreal path]

%b binary

[silver yarrow]

thats not standard is it

[surreal path]

no

[molten grotto]

its after c23

anyway try fixing the ub within that fn to see if it makes any difference

[surreal path]

theres... no ub within that fn?

[molten grotto]

you don't return anything at the end

[surreal path]

oh yeah

[silver yarrow]

wait yeah u literally dont return anything for the zero case

💀

[surreal path]

well i fixed ub

now it died

oop

now we are stuck?

[molten grotto]

when would checker be null

[surreal path]

did it call itself

[surreal path]

idk

[molten grotto]

you always set it to be address of isos[i]

that can never be null

[surreal path]

fair

ill js check if i is not 16

well my bad

looks like theres a null deref

shouldnt happen tho

[molten grotto]

do you have it mapped

it looks like you don't

[surreal path]

yes

i have mapped it

and already read one of the registers

[molten grotto]

weird

[surreal path]

yea and there is no iso

for irq 1

and it said it found something

cringe

hold on

i think i know what it is

okay i solved some skill issues

lemme solve some more skill issues

i think i solved it

nvm pressing the keyboard is doing nothing

@molten grotto how to check ioapic logs from qemu

is there like a way to do tghat

[molten grotto]

there is some trace

iirc, maybe -trace "*apic*"

[surreal path]

yea no delivered interrupts for irq 1

this should be correct

hold on

i solved the if statement that didnt solve it

hmmmmmmmmmmmmmmmmmmmmmmmmmmmm

gave this parathisis

didnt fix it

hmmmmm

yall have an idea

like any idea as to why its not working?

im going to manually try to map irq 1 in populate ioapic

and see if its the function

manually mapping it doesnt work either?

@molten grotto am i doing something wrong here?

im just manually trying to map the irq at this point

and it doesnt work

[surreal path]

thats lit the entire code

is the bit shifting in correct?

incorrect*

it doesnt look incorrect

thats assembled data in binary

ummm

why does it look like that????????????????????????

control value

i turned off bit 11

no change

value in binary

[molten grotto]

how do you know that its not working?

[surreal path]

pressing keyboard does nothing

[molten grotto]

you can look at info pic to see the status of it

[surreal path]

no interrupt is sent

k hold on

[molten grotto]

(in qemu monitor)

[surreal path]

its all masked

qwinci i think the ioapic hates me

[tawdry mirage]

true!

[surreal path]

yes!

bro the ioapic is such a simple device

how tf did i fuck this up

[kind root]

Indeed

[surreal path]

💀

[surreal path]

welp

so if everything is masked

its either

the ioapic is refusing to accpet my values

or the registers are wrong

which they arent at least

[kind root]

Show ioapic write

[surreal path]

k

well

[kind root]

Looks like you're writing zeroes

[surreal path]

thats not me?>

its just spamming this

regardless

[kind root]

Who else

[surreal path]

idk but it spams it even when booting up the vm

[molten grotto]

this isn't right, the first statement does nothing, you want to write the offset to the apic addr, value to + 0x10 like you already do

[surreal path]

oh

i forgor

💀

[molten grotto]

it literally doesn't do anything lol

it just loads some random value from some random addr and discards it

[surreal path]

it worked

but pressing the keyboard does nothing chat, maybe the keyboard queue is full?

ps2 keyboard*

time to test route irq function

[kind root]

U can test it via a fixed event handler

[surreal path]

oh thats completely wrong?

[surreal path]

wdym

[kind root]

Like an acpi interrupt for the power button

Irq 9

[surreal path]

k hold on

[kind root]

If u install the handler first ofc

[surreal path]

i pretend i do

i just report success to uacpi

[kind root]

Well route it properly

[surreal path]

seems we have a bug with the scanning of the isos

oh wait we dont

im just stupid

hold on

[kind root]

No way

[surreal path]

yea this is garbage code

i know

[kind root]

[surreal path]

this check is failing

[kind root]

What the fuck is it doing

[surreal path]

checking for the ioapic we need to use to route the irq

[kind root]

💀

[surreal path]

yea

really stupid

but it should work

[kind root]

Most readable nyaux code

[surreal path]

nah this is probs the worst nyaux code ive written

i just want to this work lol

[kind root]

Why dont u clean it up

You're speedrunning it

[surreal path]

cause i wanna write ec so bad

[finite summit]

bro I thought obos code was unreadable (it is)

[kind root]

☠️

[surreal path]

ioapic is BORING 😡

/j

[finite summit]

yet required for the EC...

[surreal path]

[finite summit]

and trust me, EC is boringer

[surreal path]

sure

[finite summit]

I've made a driver

for EC

You haven't

[surreal path]

flex

[finite summit]

Trust me it's the most plain shit you can do

[surreal path]

much

okay fine ill clean up the if statement

ummm

is bro stuck

or smt

thanks ubsan

got it working

how to make ubsan shut up

its not out of bounds?

[finite summit]

__attribute__((no_sanitize(undefined)))

[surreal path]

no

[finite summit]

shift out of bounds

[kind root]

Id trust it

[finite summit]

^^

[surreal path]

the shift out of bounds is on purpose?

[finite summit]

why

[surreal path]

16

[finite summit]

I don't need to shift out of bounds for my ioapic code

[finite summit]

that's not out of bounds

also

you did it wrong

[kind root]

Out of bounds means higher than width of type

[surreal path]

explain

[finite summit]

it's not 16 >> thing

lmao

[surreal path]

OHHHHHHHHHHHH

[finite summit]

it's thing >> 16

☠️

[surreal path]

thanks

💀

[finite summit]

nyaux moment

[surreal path]

truly

thanks

im happy i added ubsan

without ubsan i would be cooked

[tawdry mirage]

also why duplicate the expression instead of using the variable

[surreal path]

because my brain is fried

ill clean up the code

[finite summit]

unfry it

[surreal path]

lol

[finite summit]

btw, nyauxmaster, people would probably stop seeing your kernel as some cursed mess if you stopped posting a message for each small bug

*20 messages

[surreal path]

im sorry i just

i dunno

[finite summit]

nah I'm not complaining

I'm trying to say, if you always depict your kernel as having infinite bugs, that's how people will see it, if you don't want that, stay more quiet about your bugs

[surreal path]

ill try to

but again that will be difficult

[finite summit]

but no one here minds the spam usually

[silver yarrow]

I dont see it as a mess cuz of bugs

bugs are normal

[finite summit]

^

[silver yarrow]

the mess is this https://github.com/rayanmargham/NyauxKC/blob/master/kernel/src/sched/sched.c

[surreal path]

whats wrong with the sched

it is the best sched

we love sched

[silver yarrow]

like if it works for you its fine and I am not here to shit on you but to me the code is barely readable

[finite summit]

[hexed mango]

One day ill get you to read ULE

[flat nymph]

Some variable names are weird

[surreal path]

https://tenor.com/view/kasane-kasane-teto-pear-teto-meme-teto-gif-15508163395299560194

[finite summit]

I should read ULE

[surreal path]

whats wrong with e

[hexed mango]

And space your code out a bit

[surreal path]

and him

and hey

[surreal path]

[surreal path]

fair

[hexed mango]

x3

[finite summit]

if you guys want truly unreadable code, go shit on obos instead

[silver yarrow]

and figure out a way to abstract architecture specific code

[surreal path]

i did

using macros

[flat nymph]

It's fine
If you program in Go
But you aren't

see the new variable names i added in ioapic if ur scared of that

[silver yarrow]

oh god the error bubbling in go

nightmares

[finite summit]

like nyauxmaster can read his code
I have put "Abandon all hope, ye who enter here" to some files because not even I can read it

[surreal path]

[finite summit]

static int pnp_pci_driver_cmp(const void* a_, const void* b_, void* udata)

    OBOS_UNUSED(udata);
    // NOTE(oberrow): If this fails, gl and have fun.
    const pci_hid* a = &((struct pnp_device*)a_)->pci_key;
    const pci_hid* b = &((struct pnp_device*)b_)->pci_key;
    if (((int8_t)a->indiv.classCode - (int8_t)b->indiv.classCode) != 0)

    return 0;
}```

[flat nymph]

To me it's ok because of defer

[silver yarrow]

they should unironically make a way to bubble errors with one statement or something

ehhh

ig

I had one project

I did in go

[silver yarrow]

20% of the code was bubbling errors

[flat nymph]

You haven't used C++ without exceptions

[silver yarrow]

I dont use C++

fuck C++

go over c++ any day

[surreal path]

the joke is real

i am indeed

fucking nyaux

[flat nymph]

Go is 10x better after you experience that

[silver yarrow]

fair

[silver yarrow]

real

[surreal path]

and yall can never do it as good as me

😡

[silver yarrow]

though I dont suggest writing a compiler in C. I got pretty far and it is a nightmare

lol

[finite summit]

are you nyauxsexual?

attracted to nyaux

[surreal path]

real

[surreal path]

YESSS

[flat nymph]

I miss templates and "proper" (as if it is in C++ ) type system though

[surreal path]

girls ❌

nyaux

✅

[hexed mango]

I will never willjngly touch go

[surreal path]

anyways its time for EC??

chat

just cleaned up the ioapic code

[finite summit]

the only thing I have missed from C++ is RAII

[flat nymph]

It's very nice for network stuff

[flat nymph]

And that yeah

[surreal path]

first off i gotta learn what a embedded controller actually DOES

then figure out how to talk to it

then yea

[finite summit]

you have three hobby EC drivers

read any of them

[flat nymph]

Because of its threading model

[hexed mango]

Networks are for weirdos, all the real homies use completely disconnected systems

[finite summit]

like this one

(daily obos shilling complete)

[surreal path]

i need to learn what it actually does tho @finite summit

[flat nymph]

Wikipedia has an article on it

[surreal path]

okay

[finite summit]

basically it's so that AML can do IO to firmware stuffs

[flat nymph]

Because of that, ChatGPT should also be able to explain it

[finite summit]

and also so firmware can tell you when certain events happen

such as laptop lid close/open, battery status, etc.

[silver yarrow]

chatgpt: 20 great articles -> one acceptable article

[surreal path]

oh i seeee

[flat nymph]

Power button

[surreal path]

whats a acpi gpe

[silver yarrow]

ngl I dont understand peoples fascination with turning off a computer

[flat nymph]

pmOS is second

[flat nymph]

It's very cursed and overcomplicated

[surreal path]

?

[finite summit]

general purpose event

[surreal path]

oh i see

[finite summit]

stuff like power button press

battery status change

lid open/close

FN key pressed

[silver yarrow]

thats what I am saying, ppl be putting effort into turning computer off before they have working userspace

I find it funny

[flat nymph]

I have uACPI in userspace

[silver yarrow]

based

[flat nymph]

So that's a good test that it's working I guess

[surreal path]

billions will use nyaux

once it has EC

yall better agree

https://tenor.com/view/gumi-teto-guto-temi-nuclear-bomb-gif-9707227159396581194

[surreal path]

ok sure

[elder shoal]

I senrt it in the wrogn thread

😭

[surreal path]

😭

[cinder plinth]

You can have C++ type compatibility in C

There's a flag

but yeah templates are cool

In my kernel I try to avoid classes and templates unless they make sense

Like most of the OOP code is scheduler + drivers

[wicked loom]

i have a ghost ping from here

[surreal path]

i remember someone pinging u here

but they deleted their message

sorry about that

[rigid fable]

helo mankey 👋

[wicked loom]

idc lol i was just curious what happened

[flat nymph]

His flanterm wasn't working on my PC

Which maps framebuffer at 523GB

[surreal path]

on base revision 2 yea

[surreal path]

OKAY NO MORE BEING LAZY

EMBEDDED CONTROLELR TIME

okay this makes sense

now how exactly will i talk to it?

and initizie it?

lets see the acpi spec!

oaky this makes sense

yoyoyoyo hold up

whats an smi

@finite summit do u know

[finite summit]

software management interrupt

[surreal path]

oh yeah

[surreal path]

but why is the embedded controller involved with it???

like isnt smi something that shouldnt even be ACCESSED by the kernel

plus thats a cpu thing

??????????????????????

[kind root]

U can ignore this bit, its for the bios not u

[surreal path]

oh okay

and sci?

whats that

exactly

oh yeah

makes sense

okay

i see there are 2 modes to the controller

is this something i have to worry about @kind root

[kind root]

This is the most important bit

[surreal path]

i see

[kind root]

It tells you the EC wants to run AML

[surreal path]

i see

[kind root]

SCI is what they call the acpi interrupt

[finite summit]

you can take my ec driver as a reference

https://github.com/OBOS-dev/obos/blob/userspace-work/src/uACPI/ec.c

(obos shilling complete)

[surreal path]

im good thanks

[kind root]

Nah it works lol

Or take pmos

[surreal path]

so do i have to constantly check this register?

[finite summit]

no

it generates a GPE

[surreal path]

ohhhh

okay

[finite summit]

(you'd know that if you read obos' source as a reference)

[surreal path]

so i have to make a GPE handler for the embedded controller

[finite summit]

[finite summit]

yes

[surreal path]

okay

whats the exact different betqween brust and normal mode

in this context

nvm found the section in the acpi spec

nvm

wait

what sa opsm

ospm

i have a spasm

get it

[finite summit]

OSPM is you

the kerenl

[surreal path]

ohhh

[finite summit]

*kernel

[surreal path]

do i need to constantly turn on burst enable, issue comamnds and then disable when talking to the EC?

[finite summit]

no

read obos, pmos, or managarm source

[surreal path]

i am reading it

im still confusing

confused

[finite summit]

you are confusing

[surreal path]

bru

in what situations do u use brust enable tho

burst*

???

cause i see u use it everywhere in obos

source

[finite summit]

there are three mentions of it in my ec driver

[surreal path]

yea but

i want to understand why

[finite summit]

because managarm did so

[surreal path]

lmao

sorry what is uacpi_region_rw_data

[kind root]

If u dont do burst u must do one byte per ec irq

For async commands

[finite summit]

basically

it

s

[kind root]

Thats just more code

[thorny glen]

what is IRQL_GPE

[kind root]

Oh no

[surreal path]

one byte per ec irq? aw hell nah

[finite summit]

like the data for read write

[finite summit]

the irql that GPEs happen it

*at

[surreal path]

what

is that it?

[finite summit]

and the offset

[thorny glen]

like general protection exception or am i mixing up my acronyms

[finite summit]

mixing up acronyms

[surreal path]

is this for if uacpi wants to read or write something to the EC?

or is this just a easier way to

write to the EC

and read

[finite summit]

GPE is general purpose event here

[finite summit]

yes

[surreal path]

fair

[finite summit]

it's the thing that uacpi passes to you

[thorny glen]

oh so im guessing its like your dispatch level/ipldpc

[finite summit]

when aml makes a r/w to the EC

[surreal path]

ohhh makes sense

[kind root]

Thats gpf

[finite summit]

since this is acpi-related, I decided to count it as a device IRQ (which it is), which afaik usually have higher levels

[surreal path]

well it actually looks quite simple

[finite summit]

so it's defined as 8, since that's in the middle

and I like that number

[thorny glen]

oh ok i dont have anything interesting to say about that

[surreal path]

all i need to do is,
find the ec
on gpe query ec if it wants to execute aml
thats it?

is that literarly it?

[finite summit]

one more thing

[surreal path]

what else

[finite summit]

you need to install handlers for ec read/write

[surreal path]

wdym

[finite summit]

check source

[surreal path]

sorry if this is a stupid question

[finite summit]

aml can make reads/writes to EC, but you're the one handling it

[surreal path]

okay

[finite summit]

it's what uacpi_region_rw_data does

[surreal path]

is this installed handlers for it?

[finite summit]

yes

[surreal path]

okay quite simple

i will start by creating an ec source file and stealing some of ur macros in ur source

[finite summit]

dw, I stole them from managarm

[surreal path]

lol

[surreal path]

just keeping a list of what i need to do

find ec
if it exists install handlers for read and writes to it
on handler check if sci
give aml some functions to read and write to ec

and yeah

i also see there MIGHT be an acpi table for the ec

that COULD

exist

called the ECDT?

[finite summit]

yes

but if not, you look for the EC in the acpi namespace

[surreal path]

so if it does exist find the ec via there

[kind root]

Sci

[surreal path]

yea that makes sense

[surreal path]

sci my bad*

super cool interrupt

i thought ec would be EXTREMELY difficult

[finite summit]

basically:

BEFORE NAMESPACE LOAD!!
if ECDT
  init_from_ecdt
AFTER NAMESPACE INIT!!!
if !ECDT
  init_from_namespace```

[surreal path]

but its actually easy?

[finite summit]

yes

[surreal path]

yea makes sense

[finite summit]

we were just scaring you so you don't brick your pc

[surreal path]

so why am i going to be the 4th hobby os to do it, why dont more hobby oses do it?

if its so easy

[finite summit]

because not enough people give a fuck

for good reason

[surreal path]

fair

who wants to see nyaux get ec in voice 0

[plush hearth]

since I'm bored, I'll watch

[finite summit]

qemu doesn't have it

[surreal path]

join

[surreal path]

fuck

[finite summit]

nor do any VMs, afaik

[kind root]

#575111534825439252 message

[surreal path]

whats the gpe bit?

or well

ec_gpe_idx

does that tell u which gpe is coming from the ec?

??

[plush hearth]

do you not like to sleep?

[surreal path]

no

[surreal path]

@finite summit

acpi spec does not mention it

or well

i cant find where it mentions it

[finite summit]

yes

[surreal path]

okay thanks

[finite summit]

you get it from evaluating _GPE in the EC node

and taking it as an integer

uacpi_eval_integer

[surreal path]

okay makes sense

thanks

[finite summit]

np

[surreal path]

do i have permission to yoink this function

im yoinking it

[finite summit]

sure

just check the license

make sure

[surreal path]

okay

whats ur licesne again

What is nyaux going to do with lid events

[surreal path]

uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

[finite summit]

decode it to morse code

have that as his stdin

[kind root]

True

[finite summit]

(since his keyboard driver triple faults)

[kind root]

Lmao

[surreal path]

it does not

[finite summit]

-#

[kind root]

Aml + ec events is still more reliable to get input than a ps2 driver

[finite summit]

cc @elder shoal

[plush hearth]

ps2 is really weird

[finite summit]

indeed

[plush hearth]

and seems to break in every way possible

[elder shoal]

https://tenor.com/view/ps2-startup-bios-ps2startup-gaming-gif-16262793

[finite summit]

(as Astral found out the hard way)

[plush hearth]

I discovered that the hard way in my original kernel

thanks to my annoying laptop

[kind root]

Yeah ps2 breaks all the fucking time

Thats why I wanna make a ups2

[plush hearth]

that would be very helpful

don't you already have a really good ps2 driver?

[kind root]

Yeah but its in c++ and is a mess

And not portable

[plush hearth]

ah

[kind root]

But generally it worked on everything I threw at it

[finite summit]

waiting for the day infy makes ultraos

ultraos will replace linux!1!11!1!!!

and windows!!1!!1!1

[finite summit]

speaking of

@elder shoal my laptop has native ps/2

can you send me the latest astral iso, maybe I can test it

[surreal path]

what is a address space handler

[plush hearth]

my laptop also has it because the built-in keyboard uses it

[elder shoal]

hold on lemme make a minimal iso

[surreal path]

??

[finite summit]

if that's the case, I can just download it

actually nvm

I can't

[surreal path]

anyone know

😭

[finite summit]

yes

[surreal path]

what is it

[finite summit]

@elder shoal nvm I have an astral iso

[finite summit]

shit that causes the ec driver to handle teh AML EC R/W

[surreal path]

oh okayyyy

@finite summit what is the ign bit in the ec

[finite summit]

ignored

probably

[surreal path]

so why are u writing that value to the command register

in ec_read

[finite summit]

what

[surreal path]

RD_EC

0x80

[finite summit]

yeah

that's read EC

command

[surreal path]

wait

[finite summit]

your point?

[surreal path]

am i looking at the wrong thing

[finite summit]

yes

[surreal path]

wheres data sheet for

[finite summit]

look at the command set

[surreal path]

thanks

[finite summit]

somewhere in that same chapter, idr where

[surreal path]

okay that makes sense

thanks

[finite summit]

np

[surreal path]

got these beautiful functions now

time to

make the thingys for uacpi

lol

that is done

okayyy

@finite summit what ze hell are u doing here

my brain is fried reading this

[finite summit]

skill issue

[surreal path]

😡

nah but seriously tho

[finite summit]

snprintf(method, 5, "_Q%02X", idx);```

then I evaluate method

[surreal path]

what

[finite summit]

what what

[surreal path]

???

i dont understand

wdym evulate method

why are u evulating a uacpi method

why

[finite summit]

you evaluate the method

because that's how it works

[surreal path]

and it puts it in _Q?

in its node?

[finite summit]

no

what?

[surreal path]

then whats with the _Q

[finite summit]

you have idx

that gets turned to hex

appended to _Q

[tawdry mirage]

the method name is _Qxx where xx is the number of the query

[finite summit]

thanks qookie for explaining that

my brain is fried from debugging

[surreal path]

oh my bad

sorry

this just tells uacpi we finished handling the ec gpe right?

[finite summit]

yes

(managarm does it so I do it too)

[surreal path]

okay fair

obos does it too

so i do it too

anyways ec is nearly done

ima wait til 15 minutes so i can eat the other half of my pizza

then ill finish the ec

@plush hearth no longer streaming lol

[plush hearth]

alright

[surreal path]

nyaux after being automatically better then ever other hobby os project that doesnt have ec because it has efc

ec(

ec*

[surreal path]

NEARLY DONE

JUST NEED TO MAKE THE GPE HANDLER

WE HAVE EC

@flat nymph u awake

or anyone with an ec yall awake wanna test thisss

[rigid fable]

hello nyauxmaster

[surreal path]

hi

[rigid fable]

is this true what you got bald ???

[surreal path]

no

[tawdry mirage]

so much for testing ec

[surreal path]

no hpet lol
